Summary
Abstract:
This experiment began in 1923. The land uses in the project are: 1923-66 "free" rotation, 50% cereals,50% non-cereals; since 1967 4 year rotation either fodder beet,winter wheat,potatoes,winter wheat or winter rye,winter wheat,oats,winter wheat (treatment E). Treatments: A. 2xdepth of ploughing; B.with/without lime; C. with/without phosphate; D. with/without stable manure; E. crop rotation. A,B,C ... from 1923; D since 1939; E since 1967. The site is classified in the cool temperate climatic region. The average climatic conditions at the experimental site are: Minimum annual temperature: 5.7 deg C Mean annual temperature: 9.2 deg C Maximum annual temperature: 12.7 deg C Minimum annual rainfall: 356 mm Mean annual rainfall: 547 mm Maximum annual rainfall: 736 mm The soil at the site is described as an Albic Luvisol (FAO). The characteristics of the soil are: Ap 0-30 cm: silty sand, single grain structure; Al 30-50 cm: silty sand, single grain structure; al/IIBt 50-60 cm: silty/loamy sand, single grain/subpolyhedric structure; IIbt 60-80 cm: loamy sand, single grain/subpolyhedric structure; IICv >80 cm: loamy sand, single grain/subpolyhedric structure. The measurements made, methodology, and frequency are listed below: a) Vegetation measurements made and frequency Yield: Annual Total above-ground dry matter: Annual 1967-70: N,P,K. 1989/89: Cd,Pb,Cu,Zn (selected treatments). b) Soil sampling Details of soil sampling method: 25 single samples are taken per plot using an auger, combined to give a mixed sample. The samples are generally taken from 3 replications (nos 4,5,6; ie 96 plots) at irregular intervals, depending on special research projects. Due to the large number of treatments (32) sampling is sometimes limited to selected treatments. Soil is separated into layers Details of measuring depths and soil layers: 0-16,16-30,30-50 cm. The frequency of sampling is generally the same for all layers. c) Soil measurements made and frequency Total carbon: Irregular - 1937,52,56,62,67,70,88,89,90. Method of measuring total carbon: Different methods used during the course of the experiment. The latest sampling used gas chromatographic determination of CO2 and N2 after dry combustion of soil (with Nitrogen Analyser Carlo Erba 1500). Total nitrogen: Irregular (1937,52,56,62,67,70,88,89,90). Method of measuring total nitrogen: Methods have varied during the course of the experiment. Total mineral nitrogen: 1989,1990 only Method of measuring total mineral nitrogen: NO3 - Na-Salicylate method; NH4 - Nessler's Reagent Soil bulk density or weight: Irregular (1961/2,67-70,88) Other nutrients: pH (1923,26,29,31,32,34,39,46,47,52,56,62,67,70,75,85,88,89, 90). P (1924,32,38,49,52,56,62,67,70). K (1924,32,38,56,62,67,70). Ca (1956). Mg (1956). Cd,Pb,Cu,Zn (1988/89). Atmospheric inputs: Measurements of nutrient inputs (several anions and cations) contained in rainfall are available (long term values from other experiments in the research station). Other measurements: Soil: several microbiological parameters (1988-90). Plant: sociology of weeds (1988-90); investigaations into the yield structure of cereals (ears/sq m, 1000 grain weight, grains/ear, grains/sq m, nos of fertile and sterile spikelets, etc), since 1967. d) Details of the meteorological station Nearest meteorological station to the site: Berlin-Dahlem which is .5 km from the site at coordinates 13deg18min E, 52deg28min N. Meteorological data is available from both a manual and an automaticstation. e) Meteorological data available and frequency Rainfall: Daily Air temperature: Daily/continuous Soil temperature: Daily/continuous at Several depths depth Wind speed: Continuous Net Radiation: Continuous Sun hours: Daily Relative humidity: Daily/continuous Potential evapotranspiration: Daily measured/calculated by 1953-1980: Piche, Wild, Mitscherlich. 1981-> Class A pan, Czeratzki. Calculated values by the methods of Penman, Thornthwaite, Haude. This information was compiled for the GCTE-SOMNET Database, Pete Smith, Pete Falloon, David Powlson, and Jo Smith.

Quality
Details of the plots: Width of smallest plot is 4 m Length of smallest plot is 5 m Slope: Negligible . Shape: Uniform Details of direction of cultivation: Parallel Width of Bare Strip around plot: None Width of Discard Strip around plot: 0.5 m Details of homogeneity of the plots: ... Variability is high due to 1) natural soil heterogeneity; 2) treatments, esp. line and manure fertilizing, which influence pH,SOM,nutrients very differently in the various zones of the plots. The problem is intensified by the small plot size. Some small investigations were done in the pase, but systematic research work is still missing. Details of replication, randomization: There are at least 6 replicates in the experiment. Systematic design.
